Not sure what you are talking about.

If you wish for the tank to spawn equally on both teams you can use the convar versus_tank_flow_team_variation 0.0.
As for Charger AI being superl33tpr0 in one round then in the next round he completely miss every opportunity is not related to the Director.

Director is just a fancy word for lots of timers and status checks. It does not favor any sides. However look into the competitive plugins if you want more team balance of the world, same car alarms and what not.
